Dear oPhoenixo,
Thanks for bringing up this topic.
The following ports are available for the Mini Air11:
2 x USB 3.2 Gen 1 ports
1 x USB 3.2 Gen 2 port
2 x USB-C ports (data only)
And then about your question,
Only USB4 (Type-C) supports PD fast charging protocol, although there are some USB3 that are Type-C type, their charging speed is too small to be used as a power source.
The Type C port of the Air 11 can not be used for charging because they are not USB4.
